Marek Pietrzak marekpiet at gmail.comHi, I'm trying to make my rtl dongle work with gnuradio 3.6.1 on ubuntu 12.10. I compiled both recent rtlsdr and gr-osmosdr and all installed fine. Right now I have osmosdr on the list of sources in gnuradio and want just the example FFT display. When I run it the device gets opened without errors but apparently I get no samples, because the plot is blank. The dongle is Terratec T Stick PLUS and it works ok with rtl_fm. Any hint what can be wrong? The output when running: linux; GNU C++ version 4.7.0; Boost_104900; UHD_003.004.002-0-unknown Using Volk machine: sse3_32_orc gr-osmosdr supported device types: file osmosdr fcd rtl rtl_tcp uhd Using device #0 Realtek RTL2838UHIDIR SN: 00000001 Found Elonics E4000 tuner This may be of interest - strace repeating output: poll([{fd=4, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=4, revents=POLLOUT}]) writev(4, [{"\20\0\10\0\30\0\200\4_NET_SUPPORTING_WM_CHECK", 32}, {NULL, 0}, {"", 0}], 3) = 32 poll([{fd=4, events=POLLIN}], 1, -1) = 1 ([{fd=4, revents=POLLIN}]) recv(4, "\1\0\33\f\0\0\0\0\243\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 4096, 0) = 32 recv(4, 0xa5b6de8, 4096, 0) = -1 EAGAIN (Resource temporarily unavailable) recv(4, 0xa5b6de8, 4096, 0) = -1 EAGAIN (Resource temporarily unavailable) Regards, Marek -------------- next part -------------- An HTML attachment was scrubbed...
